I have a '00 S4. As I was driving to work, I noticed the water
temperature gauge go up. Soon after, the coolant overheated warning
light came on. I pull over and the coolant in the expansion tank is
boiling. Coolant level looks fine.
What's the standard procedure for diagnosing this? Could a stuck
thermostat be the cause? Where is the thermostat, and is it easy to
do a DIY replacement?
